The engine will always kick in first no matter what, even if the engine is not cold. They all do this, be in 2 seconds after you turn the key or immediately. On a cold start, the engine has to warm as quickly as possible so that it runs as efficiently as possible, so it will stay on to accomplish this. Also, if you require heat, the engine will need to stay on more frequently. Only when the engine is warm will starting off at low speeds be under electric.

B stands for braking, as in engine braking. Since the engine usually shuts off when you are not accelerating, you do not get the usual engine braking from a traditional transmission's lower gears as you would a gas engine. Putting it into B keeps the engine on while going downhill, and keeps the continuously variable transmission on a higher RPM in order to aid you in slowing down. If you ask me, its unnecessary to do so.

Distance to empty should show up if you has a navigation equipped model on the fuel consumption screen. I am not sure if the non nav equipped models have it on the MPG area of the smaller LCD screen

Thanks for your reply

Cant find the Distance to empty on my navigation equipped model on the fuel consumption screen or anywhere thought I really don't think there is one.

I just had a 2014 RX450h while mine was in the shop and no Distance to Empty either. I think they don't put it the hybrids because the distance can be hard to calculate depending on terrain and weather and how much the engine kicks in and doesn't kick in. That is just my guess though.

Sounds like a good guess - there are just too many variables to get an accurate estimate, and people would complain if the estimate turned out to be wrong and they ran out of gas early.
